I didn't make her fat. I followed the lines of her skirt and cape. She wears a petticoat under her skirt, which makes it flair and look poofy. Her cape drapes over her shoulders, and also flairs out at the waist. Her waist is actually quite tiny. She and Elsa have the same waist size.
@prektice, are you looking for the arrows that you usually see on normal patterns? These are alpha patterns, so they won't have the arrows. If you've never made alphas before, check out the tutorial section. You can find some great help in there!
